Srinupatrickeast:hi03:32
patrickeastSrinu: hey, any luck with troubleshooting?03:32
Srinupatrickeast: in check pipeline i am using 2 jobs.while one job is running tempest tests and other job is completed at that time i am getting slave went offline. because the slave jar file is deleting while deleting the nodepool vn03:34
patrickeastSrinu: hmm thats weird, why is the jar file being deleted?03:35
Srinupatrickeast: i am seeing one case when one slave vm running temepest and next slave finished the job03:36
*** ducttape_ has joined #openstack-cinder03:37
Srinupatrickeast: i placed two job templates in one yml file03:37
Srinupatrickeast: what the slave jar file will contain03:37
patrickeastSrinu: are they trying to use the same slave VM?03:37
patrickeastSrinu: for both jobs in parallel**03:37
Srinupatrickeast: No03:38
patrickeastSrinu: so what is deleting the jar file?03:38
patrickeastSrinu: nodepool? jenkins? devstack-gate?03:39
Srinupatrickeast: while deleting the nodepool vm, other slave missing the slave jar file03:39
patrickeastSrinu: yea but what happened to the jar file? it must have been there at one point, and some service/tool removed it03:40
Srinupatrickeast: while deletion it is killing java process on other slave03:41
patrickeastSrinu: heh, yea, so how does that affect the other slave?03:41
patrickeastSrinu: are you really really sure they are different vm's?03:41
Srinupatrickeast: yes03:41
*** jungleboyj has quit IRC03:42
patrickeastSrinu: is nodepool doing the deleting?03:42
Srinupatrickeast: yes. nodepool delete the slave vms03:42
patrickeastSrinu: hmm well, it also sets up the slaves with jenkins, so maybe it is tearing down the wrong node03:43
patrickeastSrinu: i would try putting some extra debug logging into nodepool code where it is cleaning up slaves (deleting the vm, removing from jenkins, etc) and see if you can catch it changing the other slave at the wrong time03:44
Srinupatrickeast: i am using nodepool version 0.3.003:45

smcginnisxyang1: Hey!13:04
smcginnisxyang1: Do you know what the latest is with the unit test hangs?13:05
smcginnisxyang1: IIRC, the tests were being skipped but the setup for them was causing issues still?13:05
xyang1smcginnis: So I tried removing the VNX test folder completely but I can still repro the hang on my set up with a Huawei test hang13:06
nikeshmhi vipin13:06
nikeshmare you around13:06
nikeshmwhat is your irc name13:06
xyang1smcginnis: unfortunately we have not got to the bottom of it13:06
*** links has quit IRC13:07
smcginnisxyang1: OK. So either the VNX one wasn't really the cause, or there are multiple cases?13:07
nikeshmnot clear on second comment13:07
nikeshmon https://review.openstack.org/#/c/34654013:07
xyang1smcginnis: right, it is not the VNX tests that caused all these13:07
*** jwcroppe has joined #openstack-cinder13:08
xyang1smcginnis: I can try skip the Huawei tests and see what happens13:08
smcginnisxyang1: OK. I thought maybe they were just a victim. But now we need to figure out what the real root cause is.13:08
*** alonma has quit IRC13:08
xyang1smcginnis: I moved the VNX test back and removed the Huawei test and the hang did not happen on my setup, but it may still happen later13:09
xyang1smcginnis: yes, we still don't know the root cause13:09
*** uberjay has quit IRC13:10
smcginnisYeah, this is tricky. You can't go by a small sampling it seems, because just when you think it's gone it comes back.13:10

*** gouthamr has joined #openstack-cinder13:18
*** alonma has joined #openstack-cinder13:19
smcginnisflip214: Yeah, unfortunately there's some problem in the tests right now that causes them to hang intermittently. So sometimes the test run will just get killed due to timing out.13:20
smcginnisflip214: The best we can do for now is just recheck and hope it doesn't hit.13:20

*** merooney has joined #openstack-cinder13:21

flip214well, I know *why* that happens... for this pylint run the python-drbdmanage package isn't installed, so the library can't be found, so object() is used as a substitute within a try import block.16:33
flip214so I do understand _why_ it's not seen; is there some comment I can add so that pylint won't bug out because of this?16:34

* smcginnis is still looking...17:09

*** akapil has quit IRC17:11
flip214smcginnis: yeah, lots of that code moved into a library file in DrbdManage, as several clients (Openstack, openattic, opennebula, ...) need the same functionality.17:12
flip214hmmm, I guess I know what I'll do....17:12
flip214thanks for listening and your patience...17:12
flip214is there an ETA for the check failures?17:12
smcginnisflip214: That's probably why pylint is flagging it. Where it's running, it probably doesn't have that library installed.17:12
flip214yeah, exactly.17:13
smcginnisflip214: So if it ends up just inheriting from Object, there will be no _check_result defined.17:13

jgriffithI'm running against master first... figured it would be a control group.  But without data it's not much of an experiment19:20
jgriffiththink I'll start it over19:20
patrickeastcan't you use the like --until-failure option instead of a bash loop? or does that work differently?19:21
smcginnisI think I would get between 3 to 5 runs on master before I would hit it.19:21
jgriffithpatrickeast: oh... that would be cool19:21
smcginnispatrickeast: You and all your smartness!19:21
smcginnis:P19:21
jgriffithpatrickeast: but I thought that was just for the single run?19:21
patrickeastheh, dunno if it actually works for unit tests19:21
patrickeasti've used that for tempest before19:22
patrickeastjgriffith: not sure19:22
jgriffithpatrickeast: in other words youwould still have to loop the tox call I think?19:22
smcginnisBut I want to do it the hard way!!19:22
jgriffithpatrickeast: because if there's no failure... then it just exits at the end of the run19:22
patrickeastjgriffith: when i used it before i had it re-run a regex of tempest tests until they broke19:22
Swanson2 bits a time?19:22
patrickeastmaybe its a different option19:22
patrickeastone of them loops the tests until it breaks19:22

*** zhonghua-lee has quit IRC19:25
patrickeastjgriffith: mm ok, found the docs http://docs.openstack.org/developer/os-testr/ostestr.html#options  looks like it loops the test19:25
patrickeastjgriffith: buuut not sure if it actually gives any different results/output from just the bash loop19:25
jgriffithpatrickeast: well I'm going to try that :)  Awesome19:25
jgriffithoh... but that's ostestr19:26
mtreinishpatrickeast: the difference between a bash loop is the bash loop has to wait for the return code, (ie the test suite finishes) the until failure flag doesn't19:26
patrickeastmtreinish: ah gotcha19:27
smcginnisReally doesn't matter. When it hangs it just hangs. The loop is just a means to keep it going.19:27
mtreinishbut if you use ostestr and until-failure make sure you turn off subunit and pretty output, otherwise it's essentially just a bash loop with testr running serially19:27
jgriffithmtreinish: patrickeast cool... but apparantly I need to also assign concurrency if I use that19:27
jgriffithotherwise it's a single process :(19:27
patrickeastah bummer19:27
mtreinishjgriffith: that's probably the pretty/subunit thing19:28
mtreinishjgriffith: try running ostestr --nopretty --until-failure19:28
jgriffithmtreinish: oh?  `tox -epy27 -- --until-failure`19:28

mtreinishheh, the forced serialization is really a hack: https://github.com/openstack/os-testr/blob/master/os_testr/ostestr.py#L123-L161 it really is just the same as a bash loop19:38
mtreinishalthough thinking about it I wonder if I replaced subunit.run with testr run --parallel there if it would work fine19:38
